Great review for suspended divers, it's concise and easy to follow, definitely offered what it said it would.
If you have not gone diving in a long time this is definitely a great guide. I read it on the flight from LA, USA to Cairns, Australia so that I could remind myself of some of teh basic principles of diving. Good thing I did. Because We hadn't gone diving in over 5 years, my partner and I had to do a written test, thanks to the tune up guide we could answer alot of the questions and passed the test with > 90%.
We went diving and had a blast.
